Reader Ted Greshams older MacBook Pro is misbehaving. He writes:I have a 2010 15-inch MacBook Pro. I pulled out the DVD drive that I never used and installed an SSD drive. Lately, the MacBook has been crashingdisplaying a black screen and then a message that I have to restart. Did installing the SSD drive break my Mac?No. Ive seen reports of this happening with this particular modelwith and without an SSD installed.
